目的 利用Micro-CT对手舟骨骨内动脉进行可视化数字模型构建并分析其临床意义。 方法 对12例离体人体前臂标本进行动脉血管灌注，Micro-CT扫描并运用Mimics20.0软件对血管进行三维重建，并分析重建数据，整理舟骨的滋养动脉分布。 结果 （1）重建出含骨内血管的腕舟骨数字化可视模型，可自由测量舟骨和血管的解剖数据，并清晰显示滋养动脉在骨内的分布及出入点；（2）右手复合组和左手复合组中滋养血管的数目分别为（4.670±1.366）支、（3.830±0.753）支，掌侧滋养血管分别为（1.670±0.516）支、（1.330±0.516）支，背侧滋养血管分别为（3.000±1.095）支、（2.500±0.548）支。 结论 离体腕部标本动脉灌注后骨内血管三维重建能清晰显示手舟骨骨内滋养动脉的来源及空间分布，为舟骨骨折的临床研究提供了形态学基础。
Abstract
Objective To build a visual digital model of the scaphoid involving intra-arterial based on Micro-CT and analyze its clinical significance. Methods 12 cases of human forearm specimens were performed vessel perfusion. Micro-CT scan was performed and Mimics 20.0 software was used to reconstruct the blood vessels in three dimensions. The reconstructed data were collected and analyzed. Results (1) A clear digital model of the intra-arterial of scaphoid was reconstructed, which can freely measure the anatomical data of the scaphoid and blood vessels. (2)The branch number of nourishing vessels in the right-hand group and the left-hand group were (4.67±1.366) and (3.83±0.753), respectively. The branch number of palmar nourishing vessels were (1.67±0.516) and (1.33±0.516), respectively. The branch number of dorsal nourishing vessels were (3.00±1.095) and (2.50±0.548), respectively. Conclusions The three-dimensional reconstruction of intraosseous vessels can clearly show the source and spatial distribution of the nutrient arteries in the scaphoid bone, which providing a morphological basis for the clinical study of scaphoid fracture.
